[Nobuyoshi Kodera's Weekly Electric Zooma!] Finally LDAC compatible, "Complete wireless highest peak !?" Sony "WF-1000XM4"-AV Watch
Long-awaited response
Sony's wireless audio is available in three types: overhead headphones, neckband earphones, and fully wireless earphones. As a noise canceling machine, the overhead "WH-1000XM4" and the completely wireless "WF-1000XM3" are popular, but the weak point of the completely wireless is that it does not support LDAC.
LDAC is a codec that can transmit up to 96kHz / 24bit over Bluetooth, and is installed in Sony Xperia and most Walkman series. Recently, LDAC support is spreading among other companies, and it is installed in some smartphones such as Samsung, Sharp, Fujitsu, and Google. If you have a compatible product, this is a feature you definitely want to use.
"Complete wireless does not support LDAC" was a part that lags behind the overhead type, but the new model "WF-1000XM4", which will be released from June 25, will finally be equipped with LDAC.
It seems that there were many issues to be solved such as miniaturization of the chip, power consumption, antenna sensitivity, etc., but four years after the appearance of the first machine "WF-1000X", and two years from the previous work, the long-standing problem was finally solved. I can say.
Let's test the power of the WF-1000XM4, which has a completely redesigned design.
